The temperature of steam corresponds to the pressure,so that by utilizing steam at ordinary pressures the temperature to which the coke A1s heated is fixed without manipulation or attention at the proper point for driving ofi' water but not the volatile constituents of the coke. The use of steam heating means therefore, aswell as the described construction of apparatus, makes it possible for unskilled persons to determine the amount of water present in the coke-without requiring them to direct their attention to a constant manipulation of apparatus for attaining and keeping the tem erature of the-coke Within the comparative y narrow limits which are necessary for an accurate determiation of the amount of water.

into 4the determination.

The apparatus is ada ted to determine the moisture 1n coke and o course coal and permits of the use of the latter in its commercial state, that is, in lumps "without hav,

ing recourse to pulverizing. This is advantageous because 1f the coke had to be pulverized moisture would evaporate during the operation and an error would be introduced Bya'the described apparatus the determination of themoistnre in the coke is made at the place and at the important because coke and coal are usually piled in the open and a shower changes 'the amount of moisture thereinl and if thecoal or coke -were transported to be tested it l.would dry out in transit. Forthese reasons say something under which as Well as others that will be readily under-- stood it is important to provide for quickly getting the coke in commercial sizes into and out of the apparatus and the described construction provides' for this.

What I claim is:

1. Means for determining Water in coke comprising the combination of a fixed coke chamber adaptedto bev lledwith cokeof commercial size and provided with entrance and exit means capable of freely passing coke of commercial sizes, devices for sealing said means, a steam jacket co-extensive in length with the coke chamber for applying a limited degree of heat to said chamber and for heating the coke throughout its mass to uniformly drive ofi' Water from the mass, a condenser chamber adapted to containa cooling substance, a calibrated tube arranged in the condenser chamber, and means for connecting the interiors of the coke chamber and calibrated tube.

2. Means for determining water'in coke comprising the combination of a coke chamber having an opening commensurate with its cross-sectional area..and -adapted to receive coke of commercial size, steam heating means for ap lyinga limited degree of heat throughout a 1 parts of the coke chamber to uniformly drive Water from the coke, acalibrated tut connected with the coke chambei', and, a transparent condenser chamber adapted to contain a cooling duid and within the calibrated tube is arranged and throu h which it is visible, substantially as descriied. 'l In 'testimony whereof I have hereunto signed my name.
